http://d.puremagic.com/issues/show_bug.cgi?id=2104 Summary: Escape function for regular expressions Product: D Version: 2.013 Platform: PC OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: bugzilla digitalmars.com ReportedBy: gaboonviper gmx.net I've been using regular expressions extensively and found that there was no escape function in the std.regexp library. It's useful when using user input in regular expressions. Here's a simple one I built. It's probably not the most efficient one out there, but feel free to use it. string regEscape(string aExpression) { return sub(aExpression, r"[\\\.\*\+\?\^\$\[\]\{\}\(\)\|]", "\\$&", "g"); } Usage: string needle1 = r"[needle]"; string needle2 = r"(needle)"; string haystack = r"[needle] (needle)"; // find needles 1 and/or 2 in the haystack auto result = RegExp(regEscape(needle1) ~ "|" ~ regEscape(needle2)).search(haystack); Cheers, Boyd --
